Jailing the pair, Judge Jeremy Donne said: "This was no game. This was no childish folly. This was a wicked crime and one that Aliyah Weekes, you determined upon over the space of about an hour during which the victim was detained.

"This was a revenge rape and this poor girl was being punished. She was accused of spreading stories. Her explanations were rejected.

"She was very distressed throughout this. She must have been terrified.

"To compound her fear was the added humiliation that all of this was happening before a group of other youths who were nearby. This was a truly wicked offence."

Aliyah was sentenced to four and a half years in a young offenders institute while her brother received five years.

The sentencing hearing was told the attack transformed the child victim from being "bubbly and carefree" to withdrawn.
